Air ducts carry conditioned air throughout a home to supply heating and cooling. Over time, many harmful contaminants like dust, mold, microbes, and chemicals can accumulate within ducts. Regular air duct cleaning helps remove these contaminants, improving indoor air quality and occupant health.
Contaminants in Air Ducts
Various contaminants can build up in air ducts, including:
•Dust: Dust particles accumulate from indoor and outdoor sources. Settled dust contains particles like skin cells, pollen, and pet dander.
•Mold: Mold spores are small and easily enter ducts. High moisture inside ducts provides an ideal environment for mold growth.
•Microbes: Bacteria and viruses are present in dust, becoming trapped in air ducts.
•Chemicals: Gases from household products evaporate and can be pulled into ductwork. Also, Chemicals like cleaning solvents and emissions from building materials also contaminate ducts over time.
Consequences of Contaminants
The contaminants that accumulate in air ducts can have negative health effects and problems like:
•Allergies and asthma: Dust, mold, and other allergens trigger symptoms for sensitive individuals.
•Illness: Microbes in ducts may cause respiratory infections.
•Odors: Chemicals and microbe growth produce musty or strange odors released through vents.
•HVAC damage: Chemical buildup and excessive dust can corrode and damage HVAC parts.
Eliminating Contaminants Through Duct Cleaning
Professional duct cleaning is the only truly effective method to thoroughly remove harmful ones from ductwork. During the process:
•Brushes: Stiff bristle brushes agitate dust and loosen particles adhering to duct surfaces.
•Vacuums: High-powered vacuums capture loosened debris and contaminants from inside ducts.
•Sanitizing: A sanitizing spray may be applied to kill microbes and inhibit future mold growth.
•Sealing: Leaks are sealed after cleaning to reduce future contamination and improve efficiency.
Benefits of Eliminating Contaminants
When harmful contaminants are successfully remove from air ducts through professional cleaning, you can expect:
•Improved indoor air quality: Reduced amounts of dust, chemicals, and other pollutants in the air you breathe.
•Lessened allergy symptoms: Lower exposure to dust mites, mold, and other triggers of asthma and allergies.
•Lower illness risk: Fewer viruses and bacteria circulating through your ventilation system.
•Better HVAC performance: Unclogged ducts allow conditioned air to flow more freely, saving energy and extending equipment life.
In summary, regular air duct cleaning every 1 to 5 years depending on conditions – helps remove harmful contaminants that degrade indoor air quality and pose health risks. Also, professional duct cleaning uses specialized equipment to thoroughly eliminate dust, mold, microbes, and chemicals from your ventilation system.
